Good question, Beemer. It's a misjudgement, I have made 32 years ago. At the time I knew not, what I know now. Good thing is, I still have the original TEC FL703-12V coils lying around and I've planned to reinstall them. Not for reasons of resistance. The Dynas force me to use R type plugs and I am not the only one that finds them less reliable than the resistor plugcaps. That is: on our bikes, which run quite rich in comparison to modern bikes. Also I find the way the caps on Dynatek wires connect to the plugs less reliable than the NGK caps do. In itself these silicone wires are superb, but the caps need these ferrules on top of the plug. This may work well under the bonnet of an automobile, but... when opposed to riding wind as on our bikes, these very supple wires move about much more than the rather stiff ones the OEM coils have. More than once I have had a bad cap-plug contact. BTW, I am eager to learn the experience of others. Pretty soon I hope to post more on our ignitions, now that a comrade on the German forum has shared his investigation.
